Description

  The present invention relates to a wall cover material support device that joins the wall surfaces of both enclosures by closing the gap between the enclosures provided in the building with a wall cover material, and functions to follow the building interlayer displacement caused by the occurrence of an earthquake, etc. It is related with the thing of the structure provided with.

  For example, as shown in FIG. 13, a plurality of sets of strip-shaped steel materials 101, 101 that pivotally support an X-shaped intersection are rotatably connected to the end surfaces of the wall cover material support device that is attached to the wall surface of the housing gap. The telescopic link mechanism 100 is configured by rotatably connecting them, and the telescopic link mechanism 100 is disposed in the gap 102, and its left and right ends are respectively connected to the left and right housings 104, 104 via hinge plates 103, 103, respectively. The left and right housings 104 are fixed and attached to the front center portion and the left and right side portions of the telescopic link mechanism 100 with the end portions overlapped with each other, and the gap 102 is sandwiched by the occurrence of an earthquake or the like. , 104 are displaced relative to each other back and forth or left and right, one or both ends of the telescopic link mechanism 100 rotate about the hinge plate 103, Alternatively, the gap 102 is closed by the wall surface cover materials 105a, 105b, and 105b that absorbs the displacement by expanding and contracting in the gap 102 and slides in conjunction with the expansion and contraction operation of the extension link mechanism 100. Those are known (for example, see Patent Document 1).

JP 2006-322132 A

The illustrated wall surface covering material support device can absorb fluctuations of the left and right housings 104, 104 sandwiching the gap 102 in the direction parallel to the width direction and the depth direction of the gap 102 by the expansion / contraction operation of the expansion / contraction link mechanism 100. Is possible.
However, in the illustrated apparatus, the left and right ends of the telescopic link mechanism 100 are fixed to the left and right housings 104 and 104 via the hinge plates 103 and 103. Therefore, the interlayer displacement of the building caused by the occurrence of an earthquake, that is, the building It is impossible to absorb the load acting on the apparatus due to the interlayer displacement by following the relative displacement in the horizontal direction generated between the upper and lower floors.

  That is, when an interlayer displacement occurs, the telescopic link mechanism 100 is tilted integrally with the left and right casings 104, 104 that are tilted in the horizontal direction, and the wall cover members 105a, 105b, 105b are tilted accordingly. Stress concentrates on the hinge plates 103, 103 connecting the mechanism 100 and the left and right housings 104, 104, damages are caused, inclined wall cover members 105a, 105b, 105b collide with each other, or the ends of both housings 104, 104 There is a risk that the apparatus may be damaged, for example, the wall surface cover materials 105a, 105b, and 105b may be removed due to the stress concentrated on the connection portion with the expansion / contraction link mechanism 100 due to collisions with the floor cover material.

In order to absorb the relative displacement along the depth direction of the gap 102 between the left and right housings 104, 104, the left and right ends of the telescopic link mechanism 100 need to be rotatably supported around the vertical axis. When the end of the telescopic link mechanism 100 is fixed to the housing 104 using the hinge plate 103 as in the illustrated device, the relative displacement along the height direction of the gap 102 between the housings 104 and 104 is absorbed in the first place. In addition, the work of attaching the hinge plate 103 to the end of the telescopic link mechanism 100 and the ends of the two housings 104 and 104 requires labor, and the construction of the wall surface covering material support device due to many processing steps. There is also a problem that the cost must be high.
As a configuration to follow the interlayer displacement, it extends in an arbitrary direction to a connection portion between the end portion of the expansion / contraction link mechanism 100 and the left and right casings 104 and 104 and a connection portion between the expansion / contraction link mechanism 100 and the wall surface cover members 105a, 105b, and 105b. It is conceivable to provide a loose hole (long hole) in combination, and to ensure a displacement margin within the range of the loose hole. However, if the size of the loose hole increases with the increase in the size of the product wall cover support device, This results in a decrease in the strength of the apparatus and cannot be applied to a large apparatus.

  In view of the above-described problems of the prior art, the present invention provides a wall cover material support device in which a gap is formed even if the left and right housings sandwiching the gap are relatively displaced in the gap width direction, depth direction, and height direction. The wall covering material can be held in the closed position, and the entire support device can be deformed following the interlayer displacement of the building, and any member constituting the device by the interlayer displacement while ensuring the member strength It is an object of the present invention to be able to be attached by a simple operation that is not easily damaged even when a direction stress is applied.

In order to solve the above-mentioned problems, the present invention attaches an expansion / contraction link mechanism that expands and contracts in the gap width direction according to the displacement of both casings in the gap between the casings, and the wall cover material attached to the expansion / contraction link mechanism makes it possible to In the wall surface cover material support device of the expansion joint for the wall that joins the wall surfaces,
A support frame that is attached to both sides of the telescopic link mechanism and has a shaft portion that projects along the height direction of the gap and projects from the end face;
A receiving member attached to the ends of the left and right housings facing the gap and having an engaging groove extending along the height direction of the gap;
The support frame is
A range in which the shaft portion engages with the engaging groove of the receiving member and is rotatably supported by the receiving member, and the shaft portion is in contact with stoppers provided at both upper and lower portions in the engaging groove. It is connected to the receiving material so that it can slide up and down along the engaging groove inside,
The support frame has a configuration in which notch portions that are not provided with projecting shaft portions are provided on both upper and lower portions of the end surface on which the shaft portion is provided.

According to this, the relative displacement along the gap width direction of the left and right housings sandwiching the gap causes the telescopic link mechanism to expand and contract, and the relative displacement along the height direction causes the end of the telescopic link mechanism together with the support frame. By sliding up and down along the receiving material, and the relative displacement along the depth direction follows the displacement in each direction by rotating the shaft part of the support frame within the engaging groove of the receiving material. The support device is displaced to hold the telescopic link mechanism in the gap, and the joining state between the wall surface cover member attached to the telescopic link mechanism and the end wall surfaces of the left and right housings can be reliably maintained.
The shaft part of the support frame that is rotatably supported in the engaging groove of the receiving material has upper and lower end parts cut out at appropriate lengths, and both upper and lower parts of the end face of the support frame. Is provided with a notch portion with the shaft portion cut away, so that when the left and right housings are inclined in the horizontal direction due to the interlayer displacement, the shaft portion of the support frame slides in the engagement groove of the receiving member, That is, the entire connection between the receiving material and the support frame slides in the tilt direction, and the support frame tilts together with the receiving material. Along with the inclination, the shaft part of the support frame slides in the engaging groove of the receiving material, and the connection position of the support frame with respect to the receiving material changes in the vertical direction. The telescopic link mechanism attached between the left and right support frames can be held on the gap without being damaged.

In the support device having the above-described configuration, the telescopic link mechanism includes a holder member having a dovetail-like engagement groove which is a tubular frame member having an appropriate length and extends along the longitudinal direction on the rear surface portion.

According to this, the expansion / contraction link mechanism is configured such that the elastic bodies attached to the left and right support frames also fasten the ends of the movable members to each other and the bolts with the compression springs attached to the shaft portions via the connecting plates. Even if the left and right housings are relatively displaced in any direction due to the occurrence of an earthquake and the like, and the load in the out-of-plane direction of the gap acts on the telescopic link mechanism, the connection The portion can be displaced along the gap depth direction to follow the deformation in the out-of-plane direction.
In addition, there is a connecting portion between the end portions of the movable material along the long hole in the gap height direction formed in the connecting plate or the long hole in the gap width direction formed in the end portion of the movable body connected to the connecting plate. Since it is provided so that it can be displaced, when the left and right housings incline in the horizontal direction due to interlayer displacement, the connecting part of the expansion and contraction body slides along the elongated hole with the inclination of the support frame connected to the receiving material. By displacing, the telescopic link mechanism can be deformed following the interlayer displacement on the gap, and the gap can be reliably closed with the wall surface cover material attached to the front surface thereof.

In the support device having the above-described configuration, instead of providing the support frame with the shaft portion and the receiving material, the support frame may have an engagement groove and the receiving material with the shaft portion.
Moreover, the expansion joint for wall surfaces of this invention has the structure by which the wall surface cover material which covers the clearance gap between the left and right housings was supported by the support apparatus of the said structure. The wall surface cover material is composed of a plurality of cover materials having a width for closing the gap, and the front surface of the telescopic link mechanism can be slid along with the expansion and contraction operation of the telescopic link mechanism in a state where the end portions overlap each other.

Since the bolt 11e is fastened and connected so as to be displaceable in the gap depth direction, the left and right housings 3 and 4 are relatively displaced in any direction due to the interlayer displacement of the building accompanying the occurrence of an earthquake, so that the telescopic link Even if a load in the out-of-plane direction of the gap 2 acts on the mechanism 11, the link portion follows the deformation in the out-of-plane direction by displacing along the gap depth direction. There will be no damage.
Further, a connecting portion between the movable members 11c and 11c is formed along the long hole 11d1 in the gap height direction formed in the connecting plate 11d or the long hole 11c2 in the gap width direction formed in the end portion of the movable material 11c. Since it is provided so that it can be displaced, when the left and right housings 3, 4 are inclined in the horizontal direction due to the interlayer displacement, the elongated holes 11d1 are accompanied by the inclination of the support frames 10, 10 connected to the receiving members 9, 9. , 11c2 can slide the connecting portion to deform the telescopic link mechanism 11 following the inter-layer displacement, and stress concentrates on the telescopic link mechanism 11 due to the load acting with the inter-layer displacement. The gap 2 can be reliably closed by the wall surface cover member 7 attached to the front surface of the telescopic link mechanism 11 without causing damage.
